Backlight assembly and liquid crystal display device with reduced noise

A backlight assembly comprising:

• a receiving container:
• a printed circuit board received in the receiving container, the printed circuit board including a plurality of conductive clips and a power supply line assembly for transmitting a lamp driving electric power, the power supply line including:
• a first conductive line electrically connected to a first subgroup of the conductive clips;
• and
• a second conductive line electrically connected to a second subgroup of the conductive clips that are not connected to the first conductive line;
• and
• a plurality of lamps combined with the conductive clips to generate light upon receiving the lamp driving electric power, wherein the first and second conductive lines are supplied with the lamp driving electric powers that have reverse phases to each other and the conductive clips of the first and second subgroups alternate with each other.

A liquid crystal display device comprising:

• a backlight assembly including:
• a receiving container;
• a first side mold on a side of the receiving container;
• a printed circuit board combined with the first side mold, the printed circuit board including a plurality of conductive clips and a power supply line assembly for transmitting a lamp driving electric power;
• and
• a plurality of lamps combined with the conductive clips to generate light upon receiving the lamp driving electric power;
• and
• a display unit that displays an image based on the light generated from the backlight assembly wherein the power supply line assembly comprises:
• a first conductive line electrically connected to a first subgroup of the conductive clips;
• and
• a second conductive line electrically connected to a second subgroup of the conductive clips that are not connected to the first conductive line, wherein the first and second conductive lines are supplied with the lamp driving electric powers that have reverse phases to each other and the conductive clips of the first and second subgroups alternate with each other.
